Explanation:
Given that,
Radius of a spherical shell, r = 0.71 m
Electric field that points radially toward the center of the sphere is 936 N/C
(a) Let q is the net charge within the sphere's surface. Using Gauss's law, we can find it :
(b) Gauss's law is used to find the amount of charge enclosed within a surface. It doesn't say anything about the distribution of the charge inside the spherical shell.
We know that in physics the momentum of an object is defined as the product of mass by the velocity of the object.
That is to say:
Where P is the momentum = 
kilograms meters/second
m is the mass
v is the object velocity = 30 m/s
In this problem we have the momentum of the roller coaster and its speed, but we want to find its mass. Then we divide the momentum between speed.
The mass is 833.33 kg
B because your supposed to bike the same direction traffic is going.
Answer:
The halogens are the family of chemical elements that includes fluorine (atomic symbol F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). The halogens make up Group VIIA of the Periodic Table of the elements. Elemental halogens are diatomic molecules.
Elements: Fluorine; Iodine; Bromine; Astatine
